Background Information

Mach is from the scrapped "Sonic the Hedgehog Band", which appeared in concept art prior to the 1991 release of the first ever Sonic the Hedgehog game; the band was supposed to play music when a player accessed the "Sound Test" option of the game.

Mach has yet to have actually been addressed by name within the comic itself; however, a female groupie can be seen carrying a sign reading "Mach rocks!" at one of the concerts.

Mach's capture and imprisonment were not seen in the comic itself, but rather detailed in the official blog.

Despite SEGA owning the rights to Mach, and therefore allowing the character to be used again in the Post-Super Genesis Wave Timeline, he has not yet made an appearance in the current comic continuity, and whether or not he will is currently unknown.
